Kate Mara ends 'Iron Man' rumor

Actress Kate Mara has sparked more speculation about her character in Iron Man 2 after revealing she is not playing Bethany Cabe.

The 24 star's role in Marvel's sequel has been kept secret since her casting was announced - prompting fans to jump to their own conclusions about who the red-headed actress would play.

When quizzed by Movieline about where the Cabe rumor came from, Mara said: "Who knows! I think Bethany Cabe in the comic book has red hair and they were like, well, Kate must be playing her. I am in Iron Man 2. I’m only in one scene, though, and it’s not Bethany Cabe."

Mara refused to be drawn on what her role was. She added: "Just check it out. I did it because they were like, 'Do you want to work with Robert Downey Jr and Jon Favreau?' I was like, 'I’ll say one word and I’m fine!' So there you go."

Iron Man 2 premieres on IMAX screens and conventional cinemas on May 7.
